provide such a method to optimize the flc parameters. An intelligent multi input multi output control for the cement milling circuit is presented. the flc is optimized by GA for varying nonlinearity in the plant. the proposed control algorithm was testedon the cement mill maintenance key performance indicators introduction It is not possible to manage what you cannot control and you cannot control what you cannot measure! performance measurement is a fundamental principle of management. the measurement of performance is important because it identifies current performance gaps betweenIn general terms, two types of raw material, such as limestone and clay, can be proportioned to fix any one parameter only, say the lsf. To fix parameters, materials of suitable composition are needed, so to control all three parameters, lsf, SR and ar, a cement works needs to blend four different materials of suitable composition.
